Product details
Overview
LM358BIDGKR from Texas Instruments is a dual general-purpose operational amplifier in VSSOP-8 package, designed for cost-sensitive industrial and consumer applications. It delivers 1.2MHz unity-gain bandwidth, 300µA/ch quiescent current, ±3mV max input offset voltage at 25°C, rail-to-rail output swing capability near ground, and operates across 3V–36V supply range - enabling use in motor control feedback, power supply monitoring, and sensor signal conditioning circuits.
For engineers reviewing the LM358BIDGKR datasheet, LM358BIDGKR pinout, LM358BIDGKR application, or LM358BIDGKR equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for design-in and BOM optimization.
Technical Context
The LM358BIDGKR implements two independent high-voltage op-amps with common-mode input voltage range extending to ground - supporting single-supply operation and direct low-side current sensing. Its internal RF/EMI filtering enhances noise immunity in electrically noisy environments like motor drives and AC inverters.
It features unity-gain stable architecture, 0.5V/µs slew rate, and 70–140 V/mV open-loop gain (typical), optimized for precision DC-coupled amplification and low-frequency closed-loop configurations such as transimpedance, comparator with hysteresis, and active filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial power rails and battery-backed systems without level-shifting. |
| Unity-Gain Bandwidth | 1.2MHz - enables stable amplification up to audio frequencies and fast-settling feedback loops in PSU error amplifiers. |
| Input Offset Voltage (max) | ±3mV at 25°C - ensures <1% error in 1V-range sensor interfaces without trimming. |
| Quiescent Current per Channel | 300µA (typ) - allows dual-amplifier operation in always-on subsystems with sub-1mA total bias current. |
| Common-Mode Input Range | Includes ground (V–) - permits direct connection of single-ended sensors referenced to system ground. |
| Output Swing (from rail) | 100mV above V– and 1.35V below V+ at 50µA load - supports accurate low-voltage signal buffering in 3.3V/5V systems. |
| ESD Rating (HBM) | ±2000V - meets IEC 61000-4-2 Level 2 for robustness in manufacturing and field-deployed equipment. |
Pinout & Package
VSSOP-8 (DGK) package: 3mm × 4.9mm body, 0.5mm pitch, exposed pad optional, RoHS-compliant, moisture sensitivity level 1.

| 3 (IN1+) | Amplifier 1 non-inverting input | Accepts reference or sensor signal; common-mode range includes ground. |
| 4 (V–) | Negative supply / ground | Reference for both amplifiers; must be connected even in single-supply operation. |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent input for second channel; identical electrical characteristics to Pin 3. |
| 6 (IN2–) | Amplifier 2 inverting input | Supports differential or inverting configuration for second signal path. |
| 7 (OUT2) | Amplifier 2 output | Electrically isolated from OUT1; shares same supply rails and thermal environment. |
| 8 (V+) | Positive supply | Supplies both amplifiers; accepts up to 36V; decoupling capacitor recommended. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358BDGKR | Same VSSOP-8 package; higher ±7mV max input offset (vs. ±3mV); no integrated RF/EMI filter. | Less suitable for noise-sensitive motor control or precision current sensing where offset drift matters. | Select when cost is primary constraint and 7mV offset is acceptable in 0–70°C ambient. |
| LM2904BIDGKR | Identical electrical specs and VSSOP-8 package; rated for −40°C to +125°C (vs. −40°C to +85°C). | Required for under-hood automotive or high-temp industrial enclosures exceeding 85°C ambient. | Choose for extended temperature operation; otherwise LM358BIDGKR offers identical performance at lower cost. |
Compared with LM358BDGKR, LM358BIDGKR improves offset accuracy and adds EMI resilience; compared with LM2904BIDGKR, it trades 125°C rating for lower unit cost while retaining all key performance metrics for commercial-temperature applications.

FAQ
What is the operating temperature range for LM358BIDGKR?
The LM358BIDGKR is specified for operation from −40°C to +85°C ambient temperature. This range covers most industrial, commercial, and consumer equipment environments, including motor drives, power supplies, and office automation devices. The device maintains its 300µA/ch quiescent current and ±3mV input offset voltage specifications across this full range, as confirmed in Section 5.3 and 5.5 of the official TI datasheet (SLOS068AB).
Does LM358BIDGKR support single-supply operation?
Yes, LM358BIDGKR supports true single-supply operation due to its common-mode input voltage range that includes the negative rail (V–), which may be grounded. Its output can swing within 100mV of V– and ~1.35V below V+, making it suitable for 3.3V, 5V, or 24V single-rail systems. This capability is explicitly documented in the "Input Voltage Range" and "Output" sections of the LM358B electrical characteristics table (Section 5.5).
Is LM358BIDGKR pin-compatible with older LM358 variants?
Yes, LM358BIDGKR uses the standard dual-op-amp pinout defined for VSSOP-8 (DGK) packages: Pins 1–4 for Amp1 (OUT1, IN1–, IN1+, V–), Pins 5–8 for Amp2 (IN2+, IN2–, OUT2, V+). This matches LM358, LM358A, LM2904, and LM2904B in DGK packaging, enabling drop-in replacement in existing VSSOP-8 footprints without layout changes.
What is the capacitive load drive capability of LM358BIDGKR?
The LM358BIDGKR is characterized to safely drive up to 100pF capacitive load without oscillation, as stated in Section 5.5 under "CLOAD". This value applies under unity-gain conditions with RL ≥ 10kΩ. For loads >100pF, external isolation resistance (e.g., 10–100Ω in series with the output) is recommended to maintain stability - a practice confirmed in TI's Application Report SLOA099.
How does the EMI filtering in LM358BIDGKR improve system-level robustness?
The LM358BIDGKR integrates on-die RF and EMI filters that attenuate high-frequency noise (typically >30MHz) coupled onto supply or input lines - critical in motor control and inverter applications where fast-switching power stages generate broadband interference. This eliminates the need for external ferrite beads or RC filters at each op-amp input, reducing BOM count and PCB area while improving immunity per IEC 61000-4-3 testing requirements.
